为了节约能源和降低成本，以下数据中心的八大能耗趋势，供您参考：
Here are the top eight data center energy consumption trends that you should consider implementing in your data center to save energy and reduce costs:
提升可再生能源的使用
Increased use of renewable energy sources
很多公司数据中心正在使用可持续能源，以实现绿色发展。例如苹果公司（Apple）与内华达能源公司（NV Energy）合作，建造了一个太阳能发电厂，为内华达州里诺市（Reno, NV）提供了200兆瓦的可再生能源。居民和企业客户可以使用高达5兆瓦的太阳能。
Many companies are implementing more sustainable energy sources in their data centers to go green. For example, Apple partnered with NV Energy to build a solar farm that provides 200 MW of renewable power to their Reno, NV location. Up to 5 MW of this solar power can be used by residential and commercial customers as well.
另一个例子是脸书（Facebook），声明希望可以100%使用可再生能源。在其位于内布拉斯加州帕皮利恩（Papillion, Nebraska）的工厂里，他们建造了一个占地55平方英里的风电厂，由101台涡轮机构成，可生产310兆瓦的电力。脸书（Facebook）还对其进行了进一步的改进，安装了一个机器学习模块，根据季节性、天气和IT能力，可以监测、预判和优化效率，这一系统使用的是可在高温环境下高效运行的服务器。
Another example is Facebook who announced they wanted to operate on 100% renewable energy sources. At their Papillion, Nebraska site they created a windfarm of 101 turbines across 55 square miles to generate 310 MW of power. Facebook has also gone a step further to improve their footprint by installing a machine learning model that will monitor, predict, and optimize efficiency based on seasonality, weather, and IT capacity, along with hyper-efficient servers that can operate under high temperature environments.
在冰岛，Verne Global公司找到了一种利用地热蒸汽发电和冰川形成的河流进行水利发电的方法，为其提供电力。它仅仅使用了系统容量10%的电力，全年较低的温度可以为其提供免费制冷。随着越来越多的公司跟进，这些方法极大地降低了能源消耗、能源成本和碳排放量。
In Iceland, Verne Global has found a way to power their location by geothermal steam and hydroelectric from glacial rivers. It only uses 10% of the available power capacity on its systems and has a low temperature that allows for free air cooling 365 days a year. These methods have reduced energy consumption, costs, and carbon footprint dramatically with more companies following suit.

增加液冷和浸没冷却的使用
Increased use of liquid and immersion cooling
随着机架密度的不断提高，随着能耗密度提升，使用CRAC/CRAH单元传统风冷模式无法将高性能计算机产生的大量热量带走。导致无法充分利用机架空间。近年来，更有效率的创新制冷方式，如液冷和浸没冷却，解决了这一问题。液体是比空气更好的导热体，能够针对特定的服务器部件，从而降低能源消耗，节省运营成本。
Rack densities are increasing and traditional, energy-intensive methods of air cooling with CRAC/CRAH units cannot remove the large amount of heat generated by high-performance compute devices. This results in not being able to utilize all the space in a rack. In recent years, more efficient cooling innovations like liquid and immersion cooling have been increasingly leveraged to solve this problem. Liquid is a better conductor of heat than air and is able to target specific server components allowing for more savings on energy consumption and operating costs.
数据中心的液体冷却方式，使用液体制冷剂将热量从服务器部件中带走，这是一种非常有效率的方法。由于存在多种不同的液体冷却方式，这已经成为业内增长最快的创新举措之一。特别是浸没冷却——将服务器部件浸没在具有高散热系数和低热阻的绝缘制冷剂中。
Data center liquid cooling is the process in which a liquid coolant is used to remove heat from server components, and it is a very efficient method. This has become one of the quickest growing innovations in the industry as there are multiple different kinds of liquid cooling. This includes immersion cooling which is when server components are submerged in a dielectric coolant that has a high coefficient of heat rejection and low thermal resistance.
传统的空气冷却法需要耗费大量的能量才可以正常工作，这会增加成本。通过使用这些新的制冷方式，可以提高数据中心的可持续性、能源效率、性能和空间利用率。它们需要更少的水资源和能源，因而可以在更小的空间内更好的支持更高的机架密度和计算容量。
Traditional air cooling methods require lots of energy to work properly which drives up costs. Implementing these newer cooling methods can benefit your data center’s sustainability, energy efficiency, performance, and utilization of space. They also require less water and energy overall and that lead to better support for higher rack densities and a more compute capacity in a smaller footprint.
数据中心的温度越来越高
Data center temperatures are on the rise
平均来讲，37%的数据中心能耗用于空气流通和制冷。ASHRAE建议服务器的入口温度在65-80°F(注18-27°C)之间，但是通常而言，为了防止设备过热导致宕机，许多数据中心都运行于底部区间，甚至低于建议温度。然而，温度过低只会浪费能源和金钱。温度每提高1°F，就可以节省4-5%的能源成本，而不会有宕机的风险。
On average, 37% of the energy consumed in the data center is for moving and cooling air. ASHRAE recommends that temperatures at the server intake should be anywhere between 65-80°F, but traditionally many data centers operated on the low end or even below those guidelines in fear of overheating equipment and causing downtime. However, overcooling equipment only wastes energy and money. For every 1° F you increase the temperature, you can save 4-5% in energy costs without risking downtime.
通过使用温度传感器和DCIM软件，现在很多数据中心的管理人员都在无风险的前提下提高了温度设置。DCIM软件通过密切监测传感器数据并触发相应操作，可以轻松的预防过度冷却。管理人员可以查看在数据中心中有哪些机柜的温度在ASHRAE建议范围之外，通过3D热延时视频轻松判定热点，并在机柜开始过热或过冷的时候自动触发阈值警报。
Now, many data center managers are increasing temperature set points without introducing any risk with temperature sensors and DCIM software. DCIM makes it easy to stop overcooling by closely monitoring sensor data and turning it into actionable insights. You can see which cabinets in your data center are operating outside of the ASHRAE range, view 3D thermal time-lapse videos to easily identify hotspots, and set automatic threshold alerts when a cabinet starts to get too cool or warm.
整合更多的数据中心
More data center consolidations
越来越多的组织机构通过整合数据中心来减少能源消耗。无论是缩小在单一房间内的设备规模，还是减少数据中心站点，都可以极大的减少碳排放量，提升效率。通过将一些数据中心的工作负载迁移到云上，降低了实际需要的物理空间。
More organizations are reducing energy consumption by consolidating your data center. Whether it’s by downsizing the equipment in a single room or by eliminating multiple data center sites, this can greatly reduce your overall footprint and boost efficiency. As some data center workloads migrate to the cloud, this reduces the amount of physical space needed.
整合空间，减少占地空间，可以有效的减少冗余系统的运营成本、采购成本、软件许可成本及维护成本。整合有可能带来风险，因此保持准确的库存容量，在搬迁前建设好新空间，跟踪全部变动，确保设备正确安装是十分重要的。
Consolidating and right-sizing into less space reduces the cost of operating redundant systems, procurement fees, software licensing costs, and maintenance costs. Consolidations can be risky, and it is important to keep an accurate inventory, build out your new space before the move, and track all changes to ensure equipment is installed correctly.
提高现有资源的利用率
Increased utilization of existing resources
由于建设新的数据中心需要更多的能源消耗和碳排放，数据中心管理人员需要提高现有资源的利用率。利用现有资源的一个重点就是恢复的闲置容量。前沿的数据中心管理人员通过使用智能机架PDU（电源分配单元）和DCIM软件，可以精确计算每台设备在数据中心中的电力消耗，从而实现设备电力消耗预算自动化。有了这些，数据中心专业人员可以在现有机架空间内安全的部署更多的服务器。
Since building new data centers requires more energy and carbon emissions, data center managers are tasked with getting more out of their existing resources. A massive step in getting more out of what you already have in your data center is recovering stranded capacity. Leading data center managers are using intelligent rack PDUs and DCIM software to automate device power budgeting by calculating an accurate power budget number for each device instance based on how they are used in the data center. With these values, data center professionals can safely deploy more servers in their existing cabinet resources.
康卡斯特公司（Comcast）通过使用这一技术，将现有资源的利用率提高了40%。此外，DCIM可以通过判定哪些运行中的服务器毫无实用功能，即僵尸服务器（ghost servers）。在一个数据中心中，高达30%的服务器都是僵尸服务器。移除这些服务器可以降低能源消耗，释放机架空间、电力、制冷和网络资源，用于部署新设备。
Comcast used this feature to get 40% more utilization out of their facilities. Additionally, DCIM helps to identify ghost servers which are servers physically running in your facility but serving no useful function. Up to 30% of the servers in a data center may be ghost servers. Decommissioning them reduces energy costs and frees up rack space, power, cooling, and network connectivity that can be used for new deployments.
增加模块化数据中心
Increased use of modular data centers
模块化数据中心产业呈指数级增长，预计到2030年，将达到890亿美元的市场规模。通过减少部署时间，增加可扩展性和能源利用率，模块化数据中心可以为传统数据中心提供更灵活、更有效的替代方案。模块化数据中心是单独的模块或容器，可以堆叠在一起，创建一个更大的数据中心。
The modular data center industry is growing exponentially and is expected to hit an 89 billion USD value by 2030. Modular data centers are designed to offer a flexible and efficient alternative to the traditional data center design by reducing deployment time and increasing scalability and energy efficiency. Modular data centers are individual modules or containers that can be stacked together to create a larger data center.
它们可以被运输到预先建好的现场，减少在现场的安装时间及搬迁时间。由于模块化数据中心不需要完整的的建筑，可以为可持续发展和提高能源利用率做出贡献。但是，配置多个模块化数据中心需要全面的数据中心远程管理策略。
They can then be shipped to a site pre-assembled which decreases the time required for physical on-site installation as well as relocated. Since modular data centers don’t require a full building to be constructed, they can positively contribute to sustainability and energy efficiency. However, having many modular data centers does present a need for a comprehensive remote data center management strategy.
提高服务器虚拟化程度
Increased virtualization of servers
现今很多公司都拥有大量的服务器，很多比较陈旧，效率较低。在虚拟环境下运营数据中心，如云上，由于物理服务器性能不同，一些虚拟的操作的运行效率也有所不同。
Companies today have large estates of servers, some being older and less efficient than others. When operating your data center like a cloud in a virtualized environment, some virtual instances may differ in performance efficiency based on the physical servers they’re on.
数据中心管理人员通过集成DCIM软件和VM软件，自动化优化虚拟服务器管理，从而提高能源利用率。数据中心的专家们通过跟踪VM软件在哪些物理服务器上运行，将虚拟程序调整到最高效的服务器上运行，可以减少能源成本。
Data center managers are increasing energy efficiency by automating and optimizing virtual machine management by integrating DCIM software with VMware. By knowing which physical servers VMs are running on, and using this information to move virtual instances to the most efficient servers first, data center professionals are saving on energy costs.
增加DCIM部署，实现可持续发展
Increased DCIM deployments to support sustainability initiatives
随着政府法规、行业规则和客户需求的变化，数据中心需要控制能源消耗，数据中心的专家们正把目光转向DCIM软件，以智能的降低能源消耗，实现可持续发展。
As governmental regulations, industry regulations, and customer demand pressure data centers to reign in their energy consumption, data center professionals are turning to DCIM software to intelligently reduce energy consumption and comply with sustainability initiatives.
DCIM软件使数据中心的管理人员可以测量能源消耗以做出更明智的决策，实时跟踪能源KPI，如能源使用效率（PUE），创建计费报告（以提高效率），避免过度制冷，识别僵尸服务器和需要被替换的高耗电设备，智能的整合和虚拟化资源，为企业的可持续发展提供数据支持。
DCIM enables data center managers to measure energy consumption and make more informed decisions, track energy KPIs like Power Usage Effectiveness (PUE) in real-time, create billback reports to facilitate more efficient behaviors, avoid overcooling, identify ghost servers and power-hungry equipment that should be replaced, intelligently consolidate and virtualize resources, and feed data into corporate sustainability reporting.
